Alfalfa Sprout Irrigation Water
Salmonella has been associated with a number of recent outbreaks of foodborne illness involving sprouted seeds. In this research, we addressed the design of sensor components intended for use in a fully automated detection system. A real−time PCR assay was developed to detect Salmonella in sprout irrigation water. Specific detection was achieved by targeting a region of the invasion gene, invA....
متن کاملEffect of irrigation with saline water on ion homeostasis and forage dry yield in Alfalfa ecotypes application of high salty water for Alfalfa plants irrigation
Salinity stress is a brutal environmental stress which decreases the yield production of plants. Questions rise on which of the ionic stress or lack of water has deleterious effects on plants forage dry yield. Also, questions remain on whether the K+ reduction or Na+ accumulation is more important in forage dry yield reduction under salinity stress. The present experiment was conducted to answe...
متن کاملDeficit irrigation for reducing agricultural water use.
At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...
متن کاملEffect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...
متن کاملModeling Microtopography in Basin Irrigation
Microtopography has long been regarded as a key variable affecting basin irrigation performance. This paper reports on the extension of a flat bed two-dimensional basin irrigation model to the simulation of irrigation events in basins with microtopography. The model incorporates the local surface slopes in the x and y directions to the governing set of partial differential equations. Three fiel...
